Actually, I believe Triumph denotes the color of Billy's bike as "Goodwood Green" and which I believe they named after the Goodwood Circuit road racing venue in England. This track is especially famous for vintage car and motorcycle racing.

(...btw, nice pics there Billy...looked like a great ride)

Yep! Just like a good Single Malt Scotch, you might call me "an acquired taste" TOO.(among the many OTHER things you may care to call me, of course)
